Metabolism is a fundamental biological process that determines the rate at which organisms process energy and materials, and determines the availability of resources for growth, maintenance and reproduction. Metabolic rates scale across levels of organization from cells to whole organisms and affect population, community, and ecosystem processes. Anthropogenic climate change and other environmental changes are predicted to have major impacts on the energetics of organisms that will be mediated through metabolic physiology. Tropical ectotherms, such as amphibians, may be among the most vulnerable to metabolic impacts of climate change as a result of being ectothermic, having high thermal sensitivity, and …

Pseudomonas aeruginosa is a Gram-negative, metabolically versatile, opportunistic pathogen that exhibits a multitude of virulence factors, and is extraordinarily resistant to a gamut of clinically significant antibiotics. This ability is in part mediated by two-component systems (TCS) that play a crucial role in regulating virulence mechanisms, metabolism and antibiotic resistance. Our sequence analysis of the P. aeruginosa PAO1 genome revealed the presence of two open reading frames, mifS and mifR, which encodes putative TCS proteins, a histidine sensor kinase MifS and a response regulator MifR, respectively. This two-gene operon was found immediately upstream of the poxAB operon, where poxB encodes …
